Kutylovsky Vladimir Alekseevich.:
- All participants are submitted; the new lock is here, a minute ago we have brought it in some shop. We open the packet and pull it out. The Lock is sealed. The lock is in open position. There are sealed keys. We shall complicate a task for ourselves - the package with keys we shall not open. We shall try the lock to close first of all. It will be made because there could be a claim that the package with keys was open and the code has been read out.
We shall check up in practice.
Now we cannot check up work of the lock at all. We insert the lock in a vice. We have to close the lock. It has to be done by using blank key. I want to specify, that time of opening does not go yet, and there is an explanation. Now we look at watch. We begin work - time went. The lock is closed on one path.
Here a key for this lock, only with one bit. It is possible to tell, that the second revolution cannot be made.
Because the key has diagonal symmetry, we can make the second bit using small file.
Now the lock is open. Look, It is opened and closed. It is necessary to take into account, that the lock have very big difference in measurements, therefore time in 19 minutes are spent.
Now we open the package with original keys and we check serviceability of the lock. The Lock works. For comparison a key, which is cut by us - from above, the bottom key - original.
Now we open the lock, and look at its contents. This is the lock, the central arrangement of a shaft of a bolt, plug, and six code elements: three code elements under a bolt and three above a bolt. System of returnable springs is cassette type.
